Semantic interoperability refers to the ability of different systems or organizations to exchange data and understand the meaning of that data in a consistent way. This ensures that information can be accurately interpreted and used across various platforms, regardless of the underlying technology. For example, when two healthcare systems share patient data, semantic interoperability allows both systems to understand the medical terms and context involved. Achieving semantic interoperability often involves using standardized vocabularies and data formats, such as HL7 or FHIR in healthcare. These standards help ensure that data is not only shared but also comprehensible, enabling better collaboration and decision-making among different stakeholders, such as healthcare providers and patients.
